IN THIS ISSUE: Susanna Eden, Reclamation Basin Study Series, Nikki Tulley, APW,
William James Shuttleworth
Long-Time WRRC Assistant Director
Susanna Eden Retires
December 17, 2020 was a bittersweet afternoon at the WRRC, as we “cyber-gathered” to bid farewell to one of our own, Assistant Director Susanna Eden. Dr. Eden (or Susanna, as everyone knows her) first joined the WRRC as a graduate student in 1988 and returned after a hiatus of a dozen years in 2005. While she wore many hats at the WRRC, she is a gifted writer and took on responsibility for the publication of the quarterly Arizona Water Resource newsletter and annual Arroyo after the retirement of long-time editor, Joe Gelt, in 2009. On December 17, dozens of Susanna’s friends and colleagues gathered on Zoom to wish her well and share memories of research projects, writing efforts, and mentoring relationships. We will miss seeing Susanna day-to-day, although she will still be engaged with the WRRC in a new, more advisory capacity in 2021. We wish her the absolute best in her future endeavors and thank her for her past contributions and professionalism, leavened always with friendship and good humor. Please feel free to continue to contact Susanna at
Brown Bag: Two-part Webinar on Water Transfers in Arizona
Date: Thursday, Jan 14, 2021
Time: 12:00 - 1:15 p.m. MST
Location: Webinar Only
Patrick Cunningham, Senior Advisor on Water Management Issues, HighGround Public Affairs
Michael J. Pearce, Partner, Gammage & Burnham, PLC
Part 1. Colorado River Water Transfers – Let's Discuss (Cunningham)
This presentation will discuss points and counterpoints of rural water issues, then look at the efforts to transfer Colorado River water rights from farmlands along the river into Central Arizona for municipal uses. The advantages of such transfers and the difficult public policy issues will also be presented.
Part 2. Transfer of Water Rights in Arizona (Pearce)
This presentation will review water transfers in Arizona, from the simple to the complex, with emphasis on agriculture to urban transfers and the unique issues associated with transferring mainstream Colorado River water.

Reclamation Article Series, Part 4: Arizona Basin Studies - Commonalities 
The following is the final installment of a four-part article series from our valued colleagues at the US Bureau of Reclamation (Reclamation). The series covers the three Basin Studies currently underway in Arizona. John Rasmussen, Eve Halper, and Valerie Swick, Water Resource Planners at Reclamation, authored the series.
Over the past three issues of the Weekly Wave, an article on each of Arizona’s three WaterSMART (Sustain and Manage America’s Resources for Tomorrow) Basin Studies (Basin Studies) was presented. The three Basin Studies are the West Salt River Valley, the Lower Santa Cruz River, and the Eloy and Maricopa-Stanfield. While each of these studies is at different stages in their analyses, they all have the same end goal: developing strategies to adapt to a changing water future. A common aspect of that future is the likelihood of less water in the Lower Colorado River system as a result of drought. These changes take place within a complicated context of water law and regulations, variable local climates, prolonged drought, and dynamic demand patterns.

Navajo Hydrologist Working to Address Indigenous Water Insecurity

Nikki Tulley, a PhD student in Hydrology at UArizona, has dedicated her life to understanding how to restore the balance between people and the environment and address water insecurity in Indigenous communities. In a short film featured last month by UArizona Office of Research, Innovation, and Impact, Tulley shares how her connection to family and her traditional upbringing in Blue Gap, Arizona, a small community on the Navajo Nation, has motivated her pursuit of hydrology. Tulley describes finding her voice as an Indigenous woman and scientist, and how the resilience of her people and their relationship to the land is a benefit as she enters the world of Western science.

BYOB at Local Schools?
Yes! AZ Project WET and Watershed Management Group are facilitating BYOB at Tucson schools as part of the Recharge the Rain (RtR) Project. However, this acronym deviates from the popular meaning and is defined as Build Your Own Basin. It is the answer to the question we asked ourselves about the core action piece of RtR, “What happens when you can no longer meet in person with students and community members to build a schoolyard rain basin?” Remote learning is bringing the opportunity to install smaller basins throughout the Tucson community. Teachers engage students in the engineering design of rain basins using the RtR rainwater harvesting curriculum. Students design rain basins to be built at their learning sites (wherever the student is currently doing the bulk of their schoolwork during COVID-19 restrictions). Where the sites and designs are feasible (determined by the teacher and RtR staff), a rain basin kit containing a tree, shrubs, native grass, and mulch is delivered. Families and students agree to install and maintain the small basins at their family homes or small schoolyards. Students will monitor and report online observations, rainfall, and heat data from their learning sites (with and without basins). The first family received their BYOB kit in December with many more kit deliveries planned for the spring. Paulo Freire Freedom School-Downtown just started a 9-week BYOB rainwater harvesting project unit with 70 students.
Remembering Jim Shuttleworth
It is with great sadness that we share the passing of William James (“Jim”) Shuttleworth, Regents Professor Emeritus of Hydrology and Atmospheric Sciences (HAS) here at the University of Arizona. Shuttleworth was a pioneer and leading expert in global hydrology and climatology. After obtaining his PhD in High-Energy Nuclear Physics, Professor Shuttleworth spent 21 years working in the UK. In 1993, Shuttleworth became a Professor of Hydrometeorology in what was at the time the Department of Hydrology and Water Resources. At UArizona, Shuttleworth's research focused on how climate change is affected by land surfaces, particularly deforestation in the Amazon basin and desert formation in Africa. Shuttleworth received many domestic and international recognitions, such as the WHO International Hydrology Prize in 2006. Shuttleworth was also director of the Center for Sustainability of Semi-Arid Hydrology and Riparian Areas (SAHRA) from 2004 to 2008. WRRC Director Sharon Megdal comments, “Jim was a tireless advocate for the advancement of research and education and a dedicated collaborator.” His gifts included a unique combination of scientific acumen and human insight. A prominent member of the HAS department, Jim Shuttleworth was a treasured colleague who will be deeply missed.
